FILTER.

Original application filed August 7, 1922,

My invention relates to improvements in filters and is particularly concerned with improvements in filters to be used on automobiles, or other automotive vehicles, for filtering the gasoline, or other fuel, before it enters the vacuum tank or carburetor, etc. v

The objects of my invention are:

First, to provide a filter, preferably of the visible type, comprising a cap, or supporting member, a filter element carried by the supporting member and areceptacle removably secured to the-cap so that it can easily and quickly be removed 1 clamped 3 the head 8, and the clam ing ring 9. This Second, to provide a filter construction,

such as described, in which the filter element is formed of 'chamois, fabric, or other flexible material, and which comprises means carried by the cap of the filter for holding the filter element in operative position;

Third, to provide a filter, such as described, from which the filter element can easily and quickly be removed and replaced with a new filter element;

Fourth, to provide a filter, such as described, in which sprin means are used for holding the filtering e ement in its operative position;

And finally, to provide afilter, such as described, that is simple. in construction and economical to manufacture.

Other objects of my invention will appear as this description progresses, reference being had to t e accompanying drawin s, in which:

igure 1 is a central, longitudinal section through one embodiment of my invention, showing it attached to a'portion of a vacuum tank; and v is I Figure 2 is a transverse section taken on line 2-2 of Figure 1.

Referring to the drawings, my improved filter comprises the receptacle 5 which is preferably formed of lass and which is more or less cup-shaped. The n per open end of the receptacle is provided with an outwardl tween the shoulder 7, formed on clamping ring is prefera l threaded onto the cap, or supporting mem er, as shown at 10, and to prevent leakage between the cap and receptacle I prefer to insert a cork, or

.adapte extending flange 6 that is' .tegral y with the boss 12.

The boss 12 has formed therein a bore 17 that communicates withthe passageway 18, formed in the cap, and the bracket member 19. This bracket member has an opening formed in its end for receiving the screw 20 by which the bracket is clamped to the cap 21 of a vacuum tank. The screw 20 is provided with a central bore 22, radial bores 23 communicating therewith, and an annular groove 24, all of which establish communication between the passageway 18 and the interior of the vacuum tank.-

The filtering element comprises a bag 25.

of chamois, o'r othersuitable filtering material. The edge of this bagis confined in the ring 26 wh ch is .of U-shaped cross sect1on and clamped to the edge of the filter bag.

A split ring 27, loosely held in an annular (giroove28 formed in the disc 15, is

to be forced into the groove to permit the ring 26 to be positioned as shown and then designed to spring outwardly to support the shown in Figure 1; If desired, a cork or other suitable gasket 29 may be confined befilter element in the posltion tween the ring 26 and the disc to prevent leakage.

For holding the filter element in distended relation, and in proper position to operetc, I rovide a tubular member 30, one end of which is slotted, as shown at 31, to form spring tongues. By inserting these 3 ring tongues into the openin 17, the to ular member 30 can be rigi y held in place. Thefother .end of this member is likewise slotted, or slitted, to form' spring tongues 32.

that are first bent outwardly and then backwardly to provide tension members for engaging the filter element 25 and holding it in proper distended shape.

In the operation of my improved filter that its contents can be emptied. If desired,

my invention, invention is not limited to these details but the fuel enters through the pipe 13, the bores 14 and the annular space surrounding the boss 12, passes around the edges of the disc 15 and into the receptacle 5. The fuel then passes through the filter element and into the assageway 17, either through the bottom 0 the slots 31 or through the bottom of the tube 30, and v then into the pipe 17 and from thence through the passageway 18 into the fuel tank.

In the course of time the lower portion of the receptacle 5 will become filled with 'water, dirt, sediment, etc., which can be readily removed simply by unscrewing the clamp ing ring 9 and removing the receptacle so the filter element can be easily removed and replaced by a new one.

This application is a division of my copending application Seriai No. 580,052, filed Aug. 7, 1922.

While I have described the details of construction of the preferred embodiment of it is to be understood that my is capable of other adaptations and modifications within the scope of the appended claims.

vided with an opening,

Having thus described my invention,what

1. A filter comprising a receptacle, a cap having an inwardly extending boss proa filter element in said receptacle, and means for securing said filter element to said cap comprising spring split spring tending to force said filter elementtoward said cap, and a member extending longitudinally of said filter element having one end inserted in said opening,

and having means at its other end to shape the filter element.

3. A filter comprising a receptacle, :1 cap having an inwardly extending boss provided with an opening, a disc secured to said boss, a filter element in said receptacle and having its upper end surrounding said disc, and a ring-shaped expansible spring adapted to force said filter element upwardly toward said cap.

4. A filter comprising a receptacle, a cap therefor having an inwardly extending boss provided with an opening, a peripherally grooved disc secured to said boss, a filter element fitting over said disc, and a split ring spring held in the groove of said disc and adapted to yieldingly press said filter clement against said disc.

In witness whereof I hereunto subscribe myfname this 23d day of September, 1925.
